Weather API

Skip to the Interactive Docs

The Weather API includes METAR, TAF (Terminal Aerodrome/Area Forecast), and Zone Forecasts.

  • METAR reports provide up-to-date information on current weather conditions at an airport; we enrich these reports with tag annotations identifying prevailing conditions and notable hazards that may impact aviation.

Our two forecast products, TAF and Zone Forecasts, are complementary in scope.

  • TAF provides a detailed forecast for the immediate vicinity of an airport, generally covering a 9 to 12 hour window (sometimes greater).
  • Zone Forecasts provide longer-term and more geographically broad outlook via day-by-day forecasts generally stretching up to about a week in the future.
